Abstract :
Analytical techniques are presented for evaluating the glint error reduction of frequency-agile tracking radars using discrete frequency-hopping. The techniques can be used to compare the tracking accuracies obtained with different procedures for frequency selection. The cases of random and cyclic frequency-hopping are worked out in detail. An illustration using a simple alpha-beta tracking filter indicates that the preferred type of frequency selection will usually depend on the filter gains used in a specific application
